Code and tests LGTM. Not sure if there's a good way to test this locally without actually wiping a device? I'm also not sure what else might fall under the umbrella of "pending activity" that we'd want to purge/ignore -- VPP installs? MDM commands?

@sgress454 MDM doesn't show up as upcoming at the moment AFAIK. There's a feature MDM is working on to make it work like that though. VPP installs use MDM commands as well

Yeah I tested it using a spare macbook air, I'm not aware of a way to fully test it without at least DEP enrolling a device
